Since the mechanical key must drive the gear assembly to move when inserted into the keyhole of the lock cylinder 209 and then rotated, there is an excessive gear resistance, so that the key cannot be rotated, and in order to avoid this, the gear base 205 can be automatically reset after the lock body 1 is automatically locked.
In order to achieve the reset effect, an idle stroke stop block 206 is arranged on the gear base 205, a limiting block 208 is correspondingly arranged at the bottom of the lock tongue peach pulling card, when the lock tongue peach pulling card is connected into the gear base 205, the limiting block 208 of the lock tongue peach pulling card can move outside the idle stroke stop block 206, so that a section of idle stroke exists between the gear base 205 and the lock tongue peach pulling card, the gear base 205 can be reversely reset under the condition that the double-leaf peach pulling card 207 is not moved, and the resistance of key turning is reduced; the angle of the contact surface between the idle stroke stop block 206 and the stop block 208 determines the idle stroke, and the other function of the idle stroke is the specific stroke angle, when the lock tongue stretches out and locks, the gear base 205 resets, so that the stop block 208 contacts with the idle stroke stop block 206, and once the motor 201 is driven, the power can be transmitted to the double-leaf shifting tongue 207 to unlock, and the idle stroke is not required to increase the waiting time for unlocking.
And the gear base 205 is connected with an outwardly extending shielding plate 210, the shielding plate 210 is located at one side of an idle stroke stop block 206, and the sensing component 6 is mounted on the moving path of the pulling tongue, the sensing component 6 is used for detecting whether the gear base 205 is successfully reset, and the shielding plate 210 is driven to rotationally cut into or cut out of the sensing range of the sensing component 6 when the gear base 205 rotates. The sensing component 6 is set as one of a mechanical switch, an ultrasonic distance sensor, a photoelectric switch or a magnetic control sensor, and in this embodiment, the sensing component 6 is set as the photoelectric switch, when the gear base 205 resets, the shielding plate 210 is driven to rotate, after the resetting is completed, the shielding plate 210 just shields the photoelectric switch, so that the photoelectric switch cannot receive the detection light beam emitted by itself, and then the control module in the lock body 1 sends reset in-place information to complete the door locking action.
In order to improve the automation degree of the lock body 1, the lock body 1 is further provided with an induction tongue 5, and an induction component 6 is arranged on the moving path of the induction tongue 5, when the door is closed, the door frame extrudes the induction tongue 5 and triggers the induction component 6, the induction component 6 can send a driving instruction for the control module to control the motor 201 in the lock body 1 to start to move, and an automatic locking function is realized.
The working principle of this embodiment is as follows:
when the door is closed, the sensing tongue 5 is extruded by the door frame and then triggers the sensing assembly 6, at the moment, the control module controls the motor 201 to start rotating and drives the gear assembly to synchronously rotate, at the moment, an idle stroke stop block 206 of the gear base 205 pushes a limiting block 208 of the double-leaf shifting tongue 207 to control the double-leaf shifting tongue 207 to start rotating clockwise, so that one shifting tongue of the double-leaf shifting tongue 207 shifts the push rod 402 to move right and drives the rotating shifting tongue 401 to rotate clockwise, and the inclined tongue 4 is pressed downwards; thereafter, the control module controls the starting of anticlockwise rotation, so that the other poking tongue of the two-leaf poking tongue 207 pokes the poking piece 303, the end part of the poking piece 303 slides along the inclined sliding groove 302 in the rotating process, and the connecting piece 301 is provided with upward movement thrust, so that the main bolt 3 is pushed out of the lock body 1, and the automatic locking function is realized. After the door is closed, the main lock tongue 3 pops up, the inclined tongue 4 resets and pops up under the action of a spring, at the moment, the motor 201 reversely rotates to drive the gear base 205 to reset, at the moment, the other idle stroke stop block 206 of the gear base 205 is contacted with the stop block 208, so that the stop block 208 of the double-leaf poking tongue 207 can directly push the idle stroke stop block 206 when unlocking, the gear base 205 immediately starts to rotate clockwise, and unlocking time can be saved; after detecting that the door is reset in place, the sensing assembly 6 sends in-place information to the control module, and the door closing action is calculated at the moment.
When the door is required to be opened, the door can be driven by the identification of the control panel or by inserting a mechanical key into a key hole of the lock cylinder 209. When the user identification is successful, the motor 201 continues to rotate reversely, the gear base 205 is driven to rotate clockwise, one of the two-leaf pulling tongues 207 pulls the pulling piece 303, and the pulling piece 303 drives the connecting piece 301 to slide downwards, so that the main bolt 3 is retracted into the lock body 1; meanwhile, the connecting piece 301 slides downwards to drive the push rod 402 to move towards the direction of the double-leaf shifting tongue 207, when the double-leaf shifting tongue 207 rotates clockwise, the other shifting tongue of the double-leaf shifting tongue 207 shifts the shifting block 403 of the push rod 402, so that the push rod 402 moves rightwards, and drives the rotating shifting tongue 401 to rotate clockwise, and the inclined tongue 4 is propped against during the clockwise rotation, so that the inclined tongue 4 is retracted into the lock body 1, and the unlocking and door opening actions can be completed at the moment.
When the sensing assembly 6 detects that the gear base 205 cannot rotate, the box body is detached from the lock body 1 integrally, and the new driving box body 2 is replaced, so that the unlocking and locking actions of the lock body 1 can be immediately recovered, the maintenance efficiency is improved, the high-level matching between all parts in the lock body 1 can be maintained after the replacement, and the stability and reliability of the lock body 1 are improved.
The above embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention are intended to be within the scope of the present invention as claimed.
